Lumbar shape factors extraction influencing the ratio of waist-darts’ volumes for young female
Wuhan Textile University, Wuhan, Hubei, 430073, China
To improve the fitness of bottoms of individuals, this study is proposed to extract lumbar shape factors influencing the ratio of waist dart’s volumes of young females. A total of 27 measurement items including lumbar shapes and waist dart’s volumes were collected through overlapped graphics of lumbar feature sections obtained from 30 female college students aged 18 and 24via 3D body scanning method. Results of correlation analysis showed that the total waist dart’s volume was significantly correlated with the lateral lumbar bending level (ytc), and the ratio of each waist dart’s volume was significantly correlated with lumbar anteversion angle (β), lumbar anteverted amount (ytq) and buttock projected volume (ab) respectively with a correlation coefficient above r=0.7. Furthermore, a total of 2 factors with a characteristic value that was larger than 1 were extracted through principle component analysis, whose cumulative contribution rate reached 80.241%. Principle Component 1 represented factors of lumbar anteversion, which was related to the ratio of anterior/posterior waist dart’s volume; and Principle Component 2 represented the lateral lumbar shape characteristics affecting the total waist dart’s volume.
